Switching device and keyboard device

A keyboard device comprising:

• a switching device including
• a rotatable actuator, and
• a contact member including an upper surface section that has a flat portion and movable in a vertical direction according to rotation of the actuator, and a deformation section that is disposed between a support member and an end portion of the upper surface section and deforms according to movement of the upper surface section,
• in a sectional view in a direction perpendicular to a rotary shaft of the actuator and parallel to the support member, a chamfer portion interconnecting a contact surface for contact with the contact member and a side surface, of the actuator, being provided between a virtual plane that contains an end portion in regard of an extending direction of the rotary shaft of the upper surface section of the contact member and that is perpendicular to the upper surface section and a virtual plane that contains an end portion in regard of the extending direction of the rotary shaft of a portion where the deformation section of the contact member makes contact with the support member and that is perpendicular to the upper surface section,
• wherein the actuator is a hammer.
